PIN LOCK Application filed May 12, 1923.

This invention relates to pin locks and in particular to a device for use in connection with jewelry pins and the like.

, A particular object of the invention is to prevent the accidental release of a pin used in connection with fancy jeweled or ornamented mountings whereby accidental loss of the same will not occur.

, A still further object of the invention is to provide in a pin look, a lip portion which prevents revolving movement of the pin lock to permit accidental disengagement thereof from the pin itself.

. A. still further object of the invention is to provide a device of the character referred to, which has few parts, which can be made up at small cost and which will securely retain the pin in its closed position.

To enable others skilled in the art to fully comprehend the underlying features of my invention that they may embody the same in the various modifications in structure and relation contemplated, a drawing depicting a preferred form has been annexed as a part of this disclosure and in such drawings, similar reference characters denote corresponding parts throughout all the views, of which,

Figure 1 is a View in perspective of an ornamental bar pin showing the application of my locking member to the pin thereof to prevent loss of the bar pin when the pin is being Worn. Figure 2 is a View of the bar pin in side elevation showing the position of the locking tongue of the pin lock.

Figure 3 is a bottom plan view of the bar pin showing how the locking tongue is arranged to pass over the pin retainer to effec tively lock itself in position over the end of the pin.

Figure 4 is a view in side elevation. showing the arrangement of the pin lock in connection with the bar pin, and V Figure 5 is a section taken on the line 55 of Figure 4, greatly enlarged, to show the position of the retaining tongue and lip of the pin look in connection with the bar pin construction.

Referring to the drawings in detail, 5 indicates the face plate of a bar pin or other piece Serial No. 277,296.

of jewelry such as a fraternity or class pin, for instance, the same having secured on the rear face thereof, the ears 6 in which is pivoted the pin 7, the pin being arranged to pierce the goods to which the ornamental member is attached to retain the same in position. The piercing end of the pin is arranged to be snapped under the hook-like pin retainer 8, the upper end of which 9, overlies the pin 7 and prevents it from opening out- 6 wardly. I

However, in the ordinary ewelry pin construction, it is very easy for the pin 7 to be come disengaged from the retainer 8 with the result that the article is lost. In order to guard against this, I have provided a pin lock which can be snapped over the end of the pin and which will effectively prevent the same from becoming separated from the pin retainer. This pin lock consists of a pin sleeve 10, the tubular wall of which is extended as at 11 to provide a lip 12, this lip being disposed on the bottom of the pin lock and being arranged, when the pin lock is in position, to rest upon the ledge 13 formed by the cut-out or hook in the pin retainer 8, this lip 12 preventing revolving movement of the pin lock and thus preventing the retaining tongue 14.- from getting in alignment. with the opening 16 in the pin retainer. It is quite so evident that if this tongue were to get into alignment with this opening, it would be a simple matter for the pin lock to slide off the end of the pin, it of course being understood that the pin lock is pushed over the end of the pin 7 between the end of the pin and the pin retainer so that the tubular portion 10 covers the end of the pin and the retaining tongue. This retaining tongue is made of spring steel and is attached to or formed in- 0 tegral with, the locking member, and eifectively prevents the latter from being accidentally forced oif the end of the pin. The retaining tonglie is provided with a depression 17 which is arranged to snap over the upper end 9 of the pin retainer 8.

The end of the pin lock is provided with a finger knob 15 through the medium of which the, tubular portion 10 thereof may be slippedover the end of the pin 7. In this 11130 position, the pin lock is effectively held in catch and a lip on the tubular portion for osition through the medium of the retainmaintaining the catch in a predetermined polng tongue 14 as is indicated in Figure 3 and sition on the end of said pin.

draws on the knob 15 sufiiciently to overcome the retaining tension of the tongue 14 causing the same to slide over the pin retainer 9 to uncover the in 7 It is uite evi ent, therefore, that I have provide a pin lock for use particularly, in connection with bar pins, clasp or fraternity pins, which is cheap to manufacture, does not have to be built into the pin, can be sold as a separate item and can be applied to practically any ornamental device using a pin for attachment of the same to the clothes of the wearer.

It is evident also that I have provided in this type of pin lock, a lip which is arranged to hold the locking member in proper relative position to the pin retaining portion so that the pin lock cannot be accidentally sli ed off the end of the pin.

hile I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is 1. The combination with a pin and pin retainer of a pin catch comprising a tubular pin engaging body and a tongue on said bod arranged to snap over said retainer for yiel ably holding the catch in place over one end of the pin.

2. A catch for use in connection with a holding pin and pin retainer comprising a tubular pin engaging body, a tongue on said body arranged to be slipped over the retainer for yieldably holding the catch in place over the end of the pin and a finger piece on said catch.

3. The combination with a device employing a fastening pin and a pin retainer having an opening therein, of a tubular member arranged to slide over the end of the pin, a spring tongue on said member arranged to pass over the pin retainer to releasably hold the tubular member in position and a lip on the member for limiting revolving movement of said member.

4. A catch for use in connection with a holding pin and pin retainer comprising a pin engaging portion, a tongue on said portion arranged to be slipped over the retainer for yieldably holding the catch in place over the end of the pin, a finger piece on said ANDRINV DURST.
